Slowness and Sparseness Lead to Place, Head-Direction, and Spatial-View Cells
We present a model for the self-organized formation of place cells, head-direction cells, and spatial-view cells in the hippocampal formation based on unsupervised learning on quasi-natural visual stimuli. The model comprises a hierarchy of Slow Feature Analysis (SFA) nodes, which were recently shown to reproduce many properties of complex cells in the early visual system []. The system extract...
متن کاملSpatial view cells in the hippocampus, and their idiothetic update based on place and head direction
Single neuron recording studies have demonstrated the existence of spatial view neurons which encode information about the spatial location at which a primate is looking in the environment. These neurons are able to maintain their firing even in the absence of visual input. The standard neuronal network approach to model networks with memory that represent continuous spaces is that of continuou...
متن کاملSpatial view cells in the primate hippocampus: allocentric view not head direction or eye position or place.
Hippocampal function was analysed by making recordings from hippocampal neurons in monkeys actively walking in the laboratory. 'Spatial view' cells, which respond when the monkey looks at a part of the environment, were analysed. It is shown that these cells code for the allocentric position in space being viewed and not for eye position, head direction or the place where the monkey is located....
متن کاملModeling Rodent Head-direction Cells and Place Cells for Spatial Learning in Bio-mimetic Robotics
We propose a computational model which is consistent with several neurophysiological findings concerning biological head-direction cells and hippocampal place cells. The model consists of two separate neural systems providing directional and place coding representations, respectively. These two modules are strongly coupled and interact with each other to form a unitary spatial learning system. ...
متن کاملRapid spatial reorientation and head direction cells.
It is surprising how quickly we can find our bearings when suddenly confronted with a familiar environment, for instance when the lights are turned on in a dark room. Subjectively, this appears to occur almost instantaneously, yet the neural processes permitting this rapid reorientation are unknown. A likely candidate is the head direction (HD) cell system. These limbic neurons found in several...
